Does Lead Electrode Placement Matter?

Good info!

But do we know what causes this difference in readout of a 12-lead core vs limb placements? I mean... the electrical values shouldn't change, as long as they are done with correct placement and symmetry.

When the LL are placed on the limbs. It allows for the electrical signals to be detected from a midline point of view relevant to the heart. The abdominal placement changes the view because the Limb leads are now anterior to the heart and mess with how the Limb leads algorithm detects electrical impulse.
